Explanation: Hitler's famously unreadable screed, Mein Kampf, actually outlines his plans for Nazi Germany in broadly recognizable terms, even if the specifics like the death camps had yet to be worked out.

It was published nearly a decade before his rise to power.

Foreign leaders still treated him as though he had very limited goals instead of what he had actually stated as his plans, all the way up until the invasion of Poland which kicked off WW2.
